Decent but dries fast
The pen works well initially, but I noticed the fluid evaporates quickly if you leave the cap off even for a minute. Need to be very careful.

Perfect for our needs
We process a lot of corrugated boxes and needed to verify corona treatment. These pens are simple to use and give immediate results.

Accurate readings
Compared these against our lab equipment and the readings were spot on. Highly recommend for anyone needing quick surface energy checks.

Good value for money
Works as expected for testing PE and PP films. The only reason for 4 stars is that the shipping took a bit longer than anticipated, but the product itself is great.

Reliable tool
I bought the set with multiple dyne levels. It makes troubleshooting coating issues very easy. The build quality feels sturdy.

Essential for quality control
We use these pens daily in our packaging line to ensure proper ink adhesion. The results are consistent and the pen lasts a long time if capped correctly.
Q: What is the shelf life after opening the pen?
A: Once opened, the solution should be used within a few months provided the cap is tightly sealed immediately after each use to prevent evaporation.
Q: Is this suitable for testing metal surfaces?
A: These pens are primarily formulated for plastics, films, and coated papers. While they might work on some treated metals, they are not optimized for bare metal surface tension testing.
Q: How do I know which dyne level pen to start with?
A: It is recommended to start with a mid-range value like 30 or 32 mN/m. If the liquid beads up, try a lower number; if it spreads evenly, try a higher number to find the exact threshold.
Q: Can these pens be refilled once empty?
A: No, these Cuiyuan Dyne Test Pens are designed for single use and cannot be refilled. Please dispose of them according to local chemical waste regulations.
Q: Do you offer a bulk discount for purchasing all levels from 22 to 36?
A: Yes, we offer special pricing for full sets and bulk orders. Please contact our sales team directly through the 'Contact Seller' button for a custom quote.
